javascript - jQuery Image Slices -

-

i've image slider, in want slice image create kind of 3d-effekt. created slider, i'm struggling responsive behavior of slider. in px values, working finde, want slider responsive. @ code , give me solution solve problem? here code:

the scss:

    /*variables & helper*/ *{     box-sizing: border-box; } %clearfix {   &:after {     content: "";     display: table;     clear: both;   } }  body, html{     margin: 0;     padding: 0;     background: url('../img/bg.png'); } img{     max-width: 100%;     height: auto; } .article{     width: 80%;     margin: 2rem auto;     background: #fff;     @extend %clearfix;     padding: .8rem; } .img__container {     float: left;     width: 100%;     margin: 0; } .slice{     float: left; }

and here javascript:

$(function(){     $( window ).on('resize',function() {         calcdimensions();         bgposition();     });     /*variables*/     var $imgcontainer = $('.img__container'),         $img          = $imgcontainer.children('img'),         slices        = 5,         percentage    = 100 / slices + '%',         imgwidth      = $imgcontainer.width(),         imgheight     = $imgcontainer.height();      /**/     sliceimg();      /*functions*/     function calcdimensions(){         imgwidth   = $imgcontainer.width();         imgheight  = $imgcontainer.height();     };     function bgposition(){         (var = 0; < slices; i++){                 $('#slice' + i).css({                     'background-position' : - ( (imgwidth / slices) * ) + 'px 0%',                 });             };     }     function sliceimg(){         var imglink    = $img.attr('src');             /* delete image */             $img.remove();              /*loop*/             /*create new divs*/             (var = 0; < slices; i++){                 var newdiv = $('<div></div>').addclass('slice').attr('id', 'slice' + i);                 $imgcontainer.append(newdiv);             };             /**/             bgposition();             $('.slice').css({                 'background-image' : 'url(' + imglink + ')',                 'width'            : percentage,                 'height'           : imgheight ,                 'background-size'  : 'cover',             });     };      });

so, if resize window, it's kind of responsive. not great real responsive experience. tried that, should right mathematic operation. in jquery can't mathematic operations %, or wrong? because i'm getting errors....

$('.slice').css({                 'background-image' : 'url(' + imglink + ')',                 'width'            : (imgwidth / slices / 100 * 1%) ,                 'height'           : imgheight ,                 'background-size'  : 'cover',             });

i'm looking forward solution. thanks!

best regards,

you said used 'px', think go if use 'em' instead of 'px'. , correct me if wrong, think might want use dootstrap responsive design.
